To all who met lu e-concerted r lie 1t known that l,. ljrnonen H. Bnontrrnn, a citizen of thelln ted tltates, residing at *fiollegeville, iii the county olt l /lontgoinery and llvtate'ol l 'ennsylvania, have invented new and useful lmprovenients in limoke and Fume rlrresters for Gras-Ttangespoi' which the following. is a specification. I

My invention relates'to a new and uselul improvement in smoke and fume arresters for gas ranges'and has for its obj'ectft o so construct such a'dev'ice as to. bring about the condensation of H101StL1I'G'a1'ld' foreign substances such as grease vapor issuing from the balre oven and broiler o t ajgasrange.

it further object of my invention is to modify the amen-(5m the oven of a gas range, thereby util zing the niammum amount of heat generated in saidoven for cooking purposes.

With these ends in view, this invention consists in the details of Construction and combination of elements hereinafter set forth, and then specifically designated by lnorder that those skilled in the art to p which this invention appertains, mayin der stand how to make and use the t T will 7 some describe its construction in detail;

This rod 3 has threads thereon "for attachment to the bridge, and passes down throu gh the center of the base. member, and is clamped, beneath the edges of thefcollar l.

through the collar land also provides for stantially the same tape as the base mem- *'ber, and has secured upon its upperportion atunnel 8,; in such a .manner as to prodi -e an annularrecess or pocket between the inof the upper end of the tlue'nipe. V

readily slip thereon and be held by a cer- 'npecifica'tio11 of LetterslPatent. lltatama'tlgnl IW'UFWMB 2235 Mgr W by the prongs 5, and when thus secured this base member becomes a permanent fixture with the gas oven.

1 The prongs 5 are inadeadjnstable by passing loosely through the clamp 5 into whicln the lower end olthe rod 8 is threaded, said red serving to hold the prongs in any adjustrnent by being screwed down thereon.

This permitsfthe'contraction and extension of "the prongs to facilitate their insertion fitting the device to ranges having various size collars. g l lcTOuTllCl the upper aortion oi the base member'is termed a head 6 for limiting the downward HlOVGIllBlltOf the flue pipe '4', the '70 lower endoit which is adapted to lit over the upperend of the base 111431111381, as clearly shown. y

The line pipe 7 extends upward on subnor walls of the funnel and the outer walls i s0 represents a collar adapted to fit within the upper end of the flue pipe; and has termed therewith the arms 10 to which are secured the lower ends o'l the retaining wires tai n amount of spring pressure, thus steady-' ing the condensing glass and holding it in place; The crossing of these wire ho'w'spermits the placing of theabsorbent' cotton 15 between the wires, and there securing: it in place. 1

- The arms 10 have their outer ends pointing upward to form prongs 1G for the reten- 105 'tion of the loweredgeot the condensing glass in position. 7

lln practwe, when the devlce 1s lJt-lllfig, used in baking or broiling the fumes emanating fromthis process will pass upward through the base member 1 and the flue pipe 7 and into the condensing glass, and when coming 1n contact with the absorbent cotton Wlll give up a certain percentage of the moisture therein, and the coarser particles of fat and other foreign substances, and as these fumes are Jompelled to flow downward, to escape around the lower'edges of the glass they will be exposed to the condensingaction of i the surfaces of the glass and all or a major portion of'the moisture and foreign substances held in suspension in the escaplng hot air will be condensed on the 1ns1de surfaces of the glass, and trickling down will The main object of securing the" base sec tion 1 permanently to the gas range is that, i when it is desired to empty the recess of the sand or ashes, which has become fouled v by the absorption of grease and the like the flue pipe may be'lifted ofi the base section for this purpose, and readily replaced.

I have found in practice that the condensing glass when in proper proportiom to the outlet from the gas ovenwill retard the draft from the oven,-thus preventing the flaringof the gas flames in said oven thereby producing'better combustion, and also holding back the outflow of the heated airwhich will decrease the consumption of gas for producing a given degree of heat in the oven, and in many cases this amounts to 25% in gassaving. i

By the use of my improvementthe grease and other-foreign substances which would pass out in vapor or suspended particles are arrested and not permitted-to reach the air in the room, and therefore'ithe walls and vfurniture are not contaminated by the cooking process, and the disagreeable odors from such cooking do not foul the air of the room.

I Ofcourse I do-not .wish to be limited to the exact details of construction as herein shown as these may be varied within the limits of the appended. claims without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as newand useful is 1. In a device of the character described,

a flue pip'e, a funnel surrounding the upper end thereofto produce a recess, a collar detachably fittedinto the upper end of the flue pipe, arms on said collar, retaining wires mounted upon said arms, and a condensing glass removably fitted over said retaining wires.

'2. In a device of the character described, a flue pipe, a funnel carried-by the upper portion thereof in such manner as to form a recess, a collar fitted within the upper end of the flue pipe, arms projecting from said collar, prongs projecting upward from the outerends of the arms, bowed retaining wires mounted upon the arms, and a condensing glass removably fitted around said retaining wires.

3. In combination with the flue pipe, a collar fitted in the upper end thereof, arms projecting from the collar, retaining wires mounted upon the arms, said wires being bowed to give a spring action, and a condensing member fitted upon said wires so as to be removable therefrom.

4 In combination with the flue pipe, a collar fitted in the upper end thereof, arms projecting from the collar, retaining wires mounted upon the arms, said wires being bowed to give a spring action, a condensing member fitted upon said wires so as to be removable therefrom, and prongs formed with the ends of thearms for embracing the lower edge of the condensing member.

In a device of the character stated, a flue pipe, a funnel carried thereby toform a recess for holding sand, a collar supported by said flue pipe, arms carried by said collar and projecting over the recess, prongs at the outer ends of said arms, a condensing glass supported by said arms and means attached to said arms and projecting into the con- 'densing glass for holding an absorbent material and retaining the condensing glass against accidental displacement.

In testimony whereof, I have hereunto affixed my signature.
